Top Officials [TOPOFF] Law and Legal Definition

Top Officials (TOPOFF) is a series of national-level domestic and international exercises designed to strengthen the U.S.'s capacity to prevent, protect against, respond to, and recover from large-scale terrorist attacks involving weapons of mass destruction (WMD.

TOPOFF includes a comprehensive program of counterterrorism training activities conducted on a two-year cycle, and involves participants and planners from across the federal interagency and international communities.

The primary goal of all TOPOFF exercises is to promote unity of effort. The Operations Directorate of the Office of the Coordinator for Counterterrorism (S/CT), within the Department of State (DOS), leads the effort to integrate the participation of both DOS and partner nations into the overall TOPOFF exercise, and ensures that Departmental and international exercise training objectives are met. TOPOFF exercises improve the capability of government officials and agencies to provide an effective, coordinated, strategic response to all aspects of a WMD attack.
